  • Be confident this part will work right. Every regulator is tested after assembly to make sure all mechanisms are working correctly.

  • Windows that don't work can be frustrating. They can also hurt your vehicles value. An inoperable window could mean $200-$500 discounted off a dealer trade value or asking price.
  • Some shops and dealers charge more for parts and repairs when they think you don't know what is involved. Now you can get the value you deserve. Knowing what this repair entails can be the difference between the value of doing it yourself, or the pain of a costly repair bill.

Very satisfied with product and service
This was my first purchase from 1A AUTO, The customer service rep was GREAT! Knew his product, listened and then responded, didnt try to outguess what I was about to say or ask. Parts shipped the same day as ordered and arrived 1 day earlier than expected, in perfect condition. Thanks to 1A Autos instructional video installation was not a problem. Lastly the parts seem to be of equal or better quality than OEM and are working as expected. Will definitely use 1A Auto again.

1aauto is awesome
These window regulators with motors were perfect. Exactly what I needed and they fit great. Super fast shipping. And the price, you cant beat it! The video provided by 1aauto was spot on and helped me. Without it, I would not have even tried doing the job myself. Thanks to all at 1aauto and keep up the great work. Wes

Perfect fit
Perfectly fitting quality parts along with a clear how-to video made this project go smoothly. Saved us $600 off of repair estimate at local shop. As a bonus, my son was fascinated to see the inside of a car door.

Got one in
Bought my daughter a 2000 Buick Lesabre with an inoperable and open passenger window. I viewed 1A’s very good video on the subject, bought the r/l pair on spec. Install went well, put the spare drivers side in the trunk for future consideration. Thanks, 1A!

Save Money and Do It Yourself
I am not a mechanic nor overtly skilled around cars. However, after watching the YouTube videos, I was fairly confident that I could fix this issue myself. I fixed my two front windows in about 30-40 minutes each. There was great satisfaction in my accomplishment, but also in my wallet. I saved $500-600 by doing it myself!
